Something like chatroulette.
A:
This is not a "Hello World"-problem, so why do you ask as if it were? What's your code, what's your problem, what's your question? If your starting from scratch, I'd advise you to start with a simple chat first and then try to put video support in it. If you've already done that you might search for JMF - Java Media Framework - it enables video support.

Does JMF have support for webcams?

actually, I don't know, it's just something that came up in the first few results of a simple google search for "java usb cam" or something like that. It should contain a USB-API so you should be able to communicate with a webcam and retrieve images from it.
